In this week's extended podcast Colin Lambert and Galen Stops dig into the details around the announcement that Citi has given notice to four of the biggest non-bank market makers in FX and discuss the potential implications for the industry.

They also find time to chat about Citi's realignment of FX and Rates, although Lambert is unsure if the changes do actually streamline the business as was apparently the intention - after all, how many people can one person effectively report to?

They close out by taking a look at the unveiling of Facebook's proposed cryptocurrency, Libra, Stops goes into details around how it will work, what the challenges are and the broader impact on the financial world, while Lambert just wonders why bitcoin is still at $9,500.
